Years ago i think i may have stumbled onto some river gold. I was 12 and in a rural area in an old creekbed there was black sand ,pyrite,quartz. I found out all these could indicate gold and that some pyrite does contain gold no gold has ever been discovered in the region not even sure if it has been prospected it lacks most gelogical indicators and topographies and any advice would be grateful I guess my question is are these enough sighn to warrant investment
